Hodges: "It could be from an ornament or a piece of jewelry."
Greg: "It could be from a lot of things."
Hodges: "Yeah, that it could, Mr. Proficiency."

Sara: "Wow. Look at you, Mr. Straightedge. I did not know that your hair could do that."Greg: "I look like a dork."
Sara: "No, no. No, you look like a pro, which is what you are."

"Between midnight and 4 a.m. what I like to call the love hours."

Sara: "Until Mia processes the sheet, there's no way to know whether the semen is the result of self-service only."
Greg: "No way. Soft porn couldn't crack that table."

Greg: "Sara, I just want you to know when we where in the shower I didn´t see anything."
Sara: "Really? Gosh! I saw everything."

"This guy is a poster child for self-love."

"No matter how hard you work to get big there is always someone bigger."

Sara: "I'll drive."
Greg: "You always do."

Hodges: "You know, far be it from me to wax nostalgic, but, uh, I kind of miss the old Greg. Ugly t-shirts, goofy hair, semi-pornographic magazines ..."
Greg: "Yeah, well, at least I had a style to change."

Hodges: "Oh, and by the way, uh ... this is just the work me. You haven't had the full David Hodges experience."
Greg: "I think I'm having it right now."

Sara: "You got it."
Greg: "And the student becomes the master."

Sara: "Technically, that makes you a cannibal. Grissom would be proud."
Greg: "Grissom would have tasted it on purpose."

Henry: "Maybe I don´t want to be a toxicologist my whole life. I mean, you went from DNA to the field, and I guess you´re kind of a role model to me."
Greg: "A role model, huh?"
Henry: "Yeah. By the way, where do you get your hair cut?"

Warrick: "I was talking to Tina the other night. She said something to make me think."
Greg: (coughs) "...Yoko Ono..."

Hodges: "Good. You are here. I love an audience."
Greg: "Don´t expect any applause."

Greg: "Nobody throws away porn. They're like heirlooms. Passed on down the family tree."

Greg: "A dame was dead, but enough about her. The air was hot and heavy with wrong, making me thirsty. Thirsty for a tall drink of water."
